I can't check ebay at work - if anyone sees a bang on polo bike and can be bothered to buy it on my behalf I can confirm a budget of £100 and could feasibly raise that to £150 if you think it's well worth it. I will reimburse my buyer accordingly :-) I presume the two that were posted two days ago have long been snapped up :(
